针对量子点复配油墨后传统电润湿驱动参数难以直接沿用,以及在持续驱动过程中量子点电润湿器件开口保持稳定性有待改善的问题,本文比较不同电压加载方式,考察双极性方波频率和正极性占空比对器件开口响应的影响,并与普通电润湿器件对照分析亮度响应,进而构建启动-维持双阶段波形。结果表明,频率和正极性占空比均会影响量子点器件的开口建立过程,且其亮度-占空比关系与普通器件明显不同;在所测试方案中,采用0.5 s、±22 V启动,随后±18 V维持时,30 s平均开口率达到73.92%,残留面积比例由基准方波的7.84%降至3.48%。在50%正极性占空比下,环境光及环境光叠加395 nm紫外光条件下的亮度分别较基准提高8.20%和20.95%。针对量子点复配后的驱动响应特性匹配启动与维持阶段幅值,可在保持有效开口的同时降低油墨残留并改善光学输出,这为量子点电润湿显示器件的针对性驱动波形设计及优化提供实验依据。
Driving parameters established for conventional electrowetting displays cannot readily be applied directly to devices incorporating quantum-dot-containing oil, and aperture retention during sustained driving requires improvement. This study compares different voltage-loading protocols, investigates the effects of bipolar square-wave frequency and positive-polarity duty cycle on aperture response, and analyzes luminance responses in comparison with those of conventional electrowetting devices. A startup-maintenance two-stage driving waveform is then developed. The results show that both frequency and positive-polarity duty cycle affect aperture formation in the quantum-dot devices, whose luminance-duty-cycle relationship differs markedly from that of conventional devices. Among the tested schemes, applying ±22 V for the first 0.5 s followed by ±18 V during the maintenance stage yields an average aperture ratio of 73.92% at 30 s and reduces the residual area ratio from 7.84% under the reference square wave to 3.48%. At a positive-polarity duty cycle of 50%, luminance increases by 8.20% under ambient light and by 20.95% under ambient light with additional 395 nm ultraviolet illumination, relative to the reference waveform. Matching the startup and maintenance voltage amplitudes to the driving-response characteristics of devices incorporating quantum dots can maintain an effective aperture while reducing residual oil and improving optical output. These findings provide an experimental basis for the targeted design and optimization of driving waveforms for quantum-dot electrowetting display devices.
